Getting GCSEs as an adult

I have a friend staying with me from another country. She is 22, very bright but has pretty much nothing in the way of qualifications (long boring story). I'd like to help her start getting some UK qualifications, but I have no idea where to look for courses...any thoughts? She is a British passport holder if that helps?

How long has she lived in UK? Gcse in English and Maths, or level 2 equivalent, are free to adults but she has to meet the residency criteria (3 years iirc) . Try your local fe college as a starting point. Even if she can't get it free she can probably pay a fee.
